Main Categories of Commodities

1. The table lists three main categories of
commodities -- Agriculture, Financial Instruments, and Natural Resources
-- and subcategories within those categories. It groups contracts by
futures and options within the categories and subcategories.

2. Exchange abbreviations are as follows:

American Commodity Exchange - ACE

AMEX Commodities Corporation - ACC

Chicago Board of Trade - CBT

Chicago Mercantile Exchange - CME

Chicago Rice & Cotton Exchange - CRCE

Coffee, Sugar & Cocoa Exchange - CSCE

COMEX Division of New York Mercantile Exchange - COMEX

Kansas City Board of Trade - KCBT

MidAmerica Commodity Exchange - MCE

Minneapolis Grain Exchange - MGE

New York Cotton Exchange - NYCE

New York Futures Exchange - NYFE

New York Mercantile Exchange - NYMEX

Philadelphia Board of Trade - PBOT

Pacific Commodity Exchange - PCE

Pacific Futures Exchange - PFE

Twin Cities Board of Trade - TCBT

MCE was previously named the Chicago Open Board of Trade. Its name was
changed effective November 22, 1972. The Commodity Exchange, Inc., became
a division of the NYMEX on July 20, 1994.

3. Most futures contracts are settled by physical
delivery of the underlying commodity. An asterisk (*) next to the
contract name means that the contract is settled in cash, based on a
price calculated by an independent third party or through a formula
specified in the contract terms. Almost all existing option contracts are
options on futures, meaning that exercise results in the establishment of
a position in the underlying futures contract; options that have the word
''physical'' after the contract name are options on
physicals, meaning that they are settled by delivery of the actual
commodity or via cash settlement. The letter (d) in the Notes column
indicates that a designated contract is dormant; i.e., the contract has
been designated for more than five years and has not traded in the past
six months. A blank space in the Notes column indicates that the contract
was traded this fiscal year and is not dormant. The letters (v) and (r)
indicate that the contract is no longer legally in force because the
designation has been vacated or revoked. ''Vacated'' contracts
are contracts for which an exchange has requested that the designation be
removed. ''Revoked'' contracts are contracts for which the
Commission has rescinded an exchange's designation.

4. The ''designation date'' is the date on
which the exchange was authorized to trade the contract (i.e., the
exchange was ''designated'' as a ''contract market'' in
that particular commodity by the CFTC or its predecessor agency). If an
exchange was previously designated by the Secretary of Agriculture as a
contract market in a commodity, and that designation was in effect on
July 18, 1975, the Commission did not specifically designate them as such
on July 18, 1975. Those designations continued in force and effect by
virtue of Section 411 of the Commodity Futures Trading Commission Act of
1974. Prior to July 18, 1975, the commodities for which designation was
granted by the Secretary of Agriculture were among the list of
agricultural and animal product commodities explicitly set forth in
Section 2(a)(1) of the Commodity Exchange Act. On July 18, 1975, the
Commission gave contract market designation to many of the exchanges
which traded in previously unregulated commodities, having given
provisional contract market designations on April 18, 1975, and having
extended such designations on May 5. The effect of the July 18, 1975,
designations was to bring under federal regulation all commodities for
which a futures contract was actively traded. Previously unregulated
commodities, such as COMEX's mercury and rubber contracts, for which
no contract market designations were granted on that date, were not
permitted to continue trading after July 18, 1975.

5. The ''trading began'' column indicates,
according to data supplied by the exchanges, when trading began in a
commodity, that is, the date of the first recorded futures or option
trading in the commodity. For many contracts, the contract terms have
changed materially since the date when trading began. A blank space in
this column means that, although approved by the Commission, the exchange
has not listed the contract for trading as of the end of the current
fiscal year.

6. The CRCE originally was the New Orleans
Commodity Exchange (NOCE). On June 15, 1983, the NOCE ceased trading and
liquidated all open commitments in all traded commodities. In September
1983, NOCE became the Chicago Rice and Cotton Exchange (CRCE). On
November 8, 1991, when the MCE was designated in rough rice futures, all
open positions in CRCE rough rice futures were transferred to the MCE
and, at the same time, all five CRCE futures contract designations were
vacated. On October 3, 1994, open positions in MCE rough rice futures
were transferred to the CBT.

11. Contract amended December 10, 1985 to
specify mandatory cash settlement in lieu of physical delivery. On June
5, 1992, the basis of the cash settlement price was changed to a USDA
price.

12. Contract amended October 25, 1995 to specify
mandatory cash settlement, based on USDA price, in lieu of physical
delivery. The contract name was also changed at that time, to lean hogs
from live hogs, since the underlying commodity was changed to hog
carcasses from live hogs.

13. On September 23, 1991, the CBT's Amex
Major Market Index (MMI) contract was renamed the MMI Mini contract. The
MMI Maxi contract was renamed the MMI contract at that time and
subsequently, on September 17, 1993, delisted from the CBT.

14. The option on the Value Line Average Stock
Index futures contract was amended to be the option on the Mini Value
Line Average Stock Index futures contract on May 28, 1992.

15. Originally designated as the
''GNMA-CD'' contract, the name was later changed to ''GNMA
II'' and then to ''GNMA.'' On April 19, 1988, this
contract was renamed as ''Mortgage-Backed Future.''

16. The underlying instrument was changed from a
three-year interest rate swap to a ten-year interest rate swap on
September 4, 1992.

17. These contracts were vacated on April 6,
1993, concurrent with Commission approval of identical CBT contracts.

18. This contract was originally named the NYMEX
Gulf Coast unleaded gasoline futures contract. It was renamed as Texas
unleaded gasoline to distinguish it from another similar contract
approved on February 11, 1992.

19. Contract size was reduced to 1 kilogram from
100 troy ounces, effective April 7, 1983. A 100-troy-ounce CBT gold
futures contract was later approved on August 11, 1987.

20. Contract size was reduced to 1,000 from
5,000 troy ounces, effective March 16, 1981. A 5,000-troy-ounce CBT
silver futures contract was later approved on August 11, 1987.

21. Contract specifications and name changed
from ''Plywood'' to ''Western Plywood,'' effective April
20, 1981.

22. The underlying commodity is a sulfur dioxide
emission allowance issued by the Environmental Protection Agency.
